Abstract
A screwing device (1) and a screwing method use a multi-member (12, 13, 14, 15) robot (6) having a driven rotational axis. The robot (6), on its last member (12), carries a rotational device (7) with a rotational tool (8). The rotational device is driven independently and is provided and designed for rapidly screwing a rotating part (3) on or off. The screwing tightening or untightening of the rotating part (3) is performed by the robot (6) and in particular by the robot end member (12).
Claims15
A working device for the rotational joining and/or loosening of rotary parts, the working device comprising:
- a multi-member robot with an end member having a driven axis of rotation;
- a tool;
- and
- an independently driven rotating device, the tool being connected to the independently driven rotating device for rotating the tool, wherein the end member of the robot carries the independently driven rotating device with the tool, wherein the independently driven rotating device defines means for rapidly screwing in or unscrewing rotary parts and wherein the robot end member defines means for tightening or untightening the rotary parts, wherein:
- the means for rapidly screwing in or unscrewing rotary parts of the rotating device and the means for tightening or untightening the rotary parts of the robot end member differ from each other in terms of speed of rotation and torque;
- the means for tightening or untightening the rotary parts of the robot end member provides a lower speed of rotation and a higher torque than the means for rapidly screwing in or unscrewing rotary parts of the rotating device;
- and
- the means for rapidly screwing in or unscrewing rotary parts of the rotating device provides a higher speed of rotation and a lower torque than the means for tightening or untightening the rotary parts.
